Evertz's father – like many others in 2012 – saw his son's ambitions to create a social media company as just another hare-brained scheme dreamt up by a schoolboy who spent too much time online.

But to test the waters, he lent Evertz $500 and gave him a simple mission: show me that you're serious.

"[My father] had his doubts, but I took that $500 and got straight into action. I went out and bought a one-page website, a sign-up book and some business cards," laughs Evertz.

"I then hit the phones and started cold-calling, as well as visiting businesses in-person for face-to-face meetings.

"After the first month I had turned over $8000, and went back to my father who said, ‘You're onto something here'."

Door-knocking with little more than ambitious idea and a business card has its challenges at the best of times – let alone doing it as an 18-year-old.

"When I first started the business I found being so young to have its advantages at times. Businesses would recognise my passion for the idea and be really supportive," Evertz says.

"But to be honest it really isn't an issue anymore. I guess people have become used to young tech CEOs – Mark Zuckerberg is a huge idol of mine – so it's less about my age and more about the business."

Big Review TV's business model has its genius in its simplicity: after recognising that soon everyone would eventually want low-cost professional video, Evertz built a content platform and then began offering to shoot slick video for small businesses at prices media agencies would openly laugh at.

"I see the growth of Big Review TV the same way I think of websites back in the early 2000s – at the time businesses were just starting to wake up and think, 'Hold on, I need a website'," says Evertz.

"Now they are saying, 'I need video for social media', and we're providing that at a scale other people haven't been able to."

Small businesses can choose a package from the Big Review TV website, and then Evertz's team will send a professional video crew to film a top-class video that owners can use for personal content, as well as appearing on the Big Review TV website.

A year's membership with all the trimmings costs a business just $299 a month, meaning Evertz is able to take a product that was once only available to corporate giants and place it in the hands of hairdressers, bakers and café owners.

"So far we've created over 30,000 professional videos for all kinds of businesses. Previously video was considered to be the Rolls-Royce of marketing, but we're bringing it to everybody," says Evertz.

But his self-evident ambition will not rest with video marketing, he wants to create an online social community capable of talking shop with the biggest networks in the world.

"Right now we're looking to build the Australian model bigger and better, but we've also just established a team in the US, which is an enormous potential market," Evertz says.

"There's also scope for the huge social potential of Big Review TV. We're currently building an app that will let users record their own video reviews and then be rewarded for that. Reviewers would also have the chance to build followings, which is key in the social space."
